The dose of thyroxine during pregnancy
Question: Good morning, six months ago was diagnosed with hypothyroidism and began taking the hormone from 50 mcg to 100 mcg. After 3 months there were unpleasant symptoms of heart-ache, nausea, weakness, sweating, lump in the throat. Passed tests: T3sv. -7. 8 (rule 3. 2-7. 2), T4 St. -19. 3 (9-22), TSH-0, 011 (norm 0. 4-4. 0), AT-TG-41 (normal less than 40), Ab-TPO-less than 10. 0 (less than 35). Reduce the dose again to 50mkg. 28 avgusa retake analysis-all in the normal dose left unchanged. We learned that she is pregnant, the period of 6 weeks. Again concerned heart and a lump in my throat, sometimes toschnit (evening), no other signs. Can it be that the thyroid gland in relation to pregnancy has earned better? Analysis prescribed me again after 2 weeks. I am very worried for the health of the baby, is not dangerous if overdosed? And what are these signs of discomfort? Perhaps, on the contrary, they suggest that a larger dose? Very worried. Will prizntelna for the answer
Answer: 1. Do not worry:) 2. During pregnancy the thyroid gland does not begin to work better – on the contrary, the demand for it increases hormones, so the dose of thyroxine to the 2 nd half of pregnancy increased from baseline by approximately 50%. These symptoms may be associated with pregnancy, about the lack of hormones, they just do not say. But the symptoms of hormone levels in the blood is difficult to pinpoint, and therefore need the hormone analysis for dose adjustment. There is really no need to change the dose of thyroxine (more so – that it can change only by a doctor to receive full-time), wait for test results (2 weeks – this is a normal period before – not needed). Then the dose will be adjusted endocrinologist on the results of tests (TSH + necessarily svT4). Overdose during pregnancy is less dangerous than the lack of hormones.
